I asked Smith on Thursday over the phone why Dallas can't seem to put it all together.

"I think the Cowboys have somewhat lost their true identity," he said. "I mean, I think the team -- we don't know if we want to be a pass team or a run team."

Smith said the difference between today's Cowboys and the potent Dallas squads of the '70s, '80s and '90s channels back to that lack of a one-two punch, saying those old teams "had tremendous success having a very balanced offensive unit."

Only the Atlanta Falcons ran the ball fewer times than the 'Boys this season. Dallas dialed up just 336 runs, compared to a swath of playoff clubs -- Seattle (336), San Francisco (505) and Philadelphia (500) -- who all finished top five in attempts. Ten of the top 15 rushing squads, in terms of carries, made the postseason in 2013.

NFL Media Insider Ian Rapoport reported last month that the relationship between quarterback Tony Romo and running back DeMarco Murray had grown "frosty" by December. Murray finished the season with the fourth-highest yards per rush (5.2) in the league, but tied for 17th in attempts.
